Julia Lawall 93026e217b arch/m68k/mm/sun3mmu.c: Eliminate NULL test and memset after alloc_bootmem 
As noted by Akinobu Mita in patch b1fceac2b9,
alloc_bootmem and related functions never return NULL and always return a
zeroed region of memory.  Thus a NULL test or memset after calls to these
functions is unnecessary.

This was fixed using the following semantic patch.
